Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
While en route, the propeller separated from the home built acft. Subsequently, the nose gear failed & the main gear were damaged during a landing on rolling terrain. An examination revealed that the mounting bolts for a propeller spacer had failed. The spacer had been installed between the engine & the propeller to offset a clearance problem.
